I am perplexed as to why. Because I have CDO installed and it is a part
of the bundle, but I do not have some optional parts of CDO installed,
like Dawn, DB40 support, Postgres support. I don't need them and they
are definitely not a part of my dependencies in MANIFEST.MF and
plugin.xml So to be clear none of the missing plugins here are used by
my plugin. So why is it trying to include them? Is there a way I can
find out where these dependencies come from?

Still cannot build my bundle due to the error below. Leaving aside why
productBuild.xml would include a source file plugin. I am not sure
where I can find this org.eclipse.core.filesystem.source_0.0.0 plugin?
